Is Maringo suffering from an insane delusion?

The following excerpt is from Maringo v. McGuirk, 2008 WL 631304 (5th Cir. 2008).  The case is actually about whether an attorney was guilty of harassment but the facts certainly make one wonder whether Maringo was suffering from an insane delusion which would render him unable to execute a valid will.

Maringo alleged that Erica McGuirk, an attorney for United States Immigration and Customs Enforcement (ICE), and her ghost, “the reincarnated Jezebel Princess of Evil,” have caused him mental distress by appearing before him, particularly while he is sleeping at night or showering. According to Maringo’s complaint, McGuirk and her ghost sexually harassed him by exposing themselves and “forcing [him] to watch or participate”; forced him to read ghost and horror literature with them; insisted that he listen to a ghost-themed radio show; and appeared with “Santa Claus hats, wings and [a] horn with shaggy, black feathers.” He alleged that after complaining about this matter, ICE officials retaliated against him by placing him in a single-person cell, where they could more easily kill him by poisoning his food.
